clearing out session variables
Posted 13 September 2006 - 03:04 PM
I seem to be having trouble assigning new values to session variables that I've created after they've received an initial values, like so:
$_SESSION['var'] = 25.5;
Then I try to do this:
$_SESSION['var'] = 30.1;
and I get as an output 0. What's with that? Thanks.

Now, what's happening is that these values are assigned on the final order page, and then for example, the customer goes back to the home page and places another order. They then submit it, and it goes to the final order page, where the order info, quantity, price, etc. are reassigned to the session varibles. Then these are read further down in the page. I don't have to do this, but some of these values are used again, so it's a convenient method.
Now, because the session variables are still holding the info from the last order, they don't seem to accept new values.
